'To all whom it may concern:

' 1' Beit {known that I, ANT ox, SfAnnEnsoii, a

,citizen of the UnitedStates, residing at Chicago, county of Cook, and Svtate of Illinois,

have invented certain new and useful Improyements inWindow-Cleaning Devices, of

which,the. following is a specification.

nlViyin-vention relates'to window cleaning devices, and particularlyto a window cleaning device for cleaning the outer surface of the; windows by a person within the room,

. I -he;-object of myin'vention is to provide a device-oi the.c lassmentioned', which shall be O Simpleconstruction and readily operated.

' ,i Other objects will appear hereinafter. With these objects in view, my invention consists generallyin a base portion adapted .t'o rest upon'a Window sill, a standard secured 'inverticalpositiontoeach end of said base, a cleaning device slidably mounted on one of said'standards and means arranged on the other standard for operating said cleaner. I

t My inventionfurther consists in a base portion, a standard secured to each end of said-base and rising vertically therefrom, a cleaning device slidablymounted on one of said standards arotar'y member on the other standard,. a cord operatively connecting said cleaner and said rotary member, and means for automatically taking up the slack in said cord.-

My 'invention further consists in various details of construction and arrangements of parts, all as will be hereinafter fully described and particularly pointed out in the claims.

My invention will be .more readily understood by reference to the accompanying drawings, forming a part of this specification, and in which- Figure-1 isaside elevation of a window,

cleaning device embodyingmy invention-in its preferred form, a portion of the window sill and the sash being shown in section, Fig.

2 is a bottom plan view of'the device, Fig. 3 1s a vertical section of the device on the line :c-a; of Fig. 1, Fig. 4 is a rear face view of the cleaner block or rubber, and Fig. 5 is-a detail section of the sliding cleaner up on an enlarged scale, the section being taken on the line P il] of Fig. 1;

fteferring now to the drawings, 1 indicates.

base portion of the device, which is preftbly quite thin, and which may be made of 5 suitable material such as wood or metal. men the device is inoperative position, the

projects beneath the sash whichis loweredupon the same. it 13 to the end that the sash may be lowered as far as possible that the base 1 is made as thin as is practical. Both'the outer and inner ends of the base portion are considerably thickened forming the raised portions 2 and 3 respectively, in which are secured the standards 4 and 5 extending vertically upwards therefrom. The cleaning device proper is slidably mounted on the outer standard a, and is moved up and down thereon to clean the window. To this end, the standard 4 is made of sufficient height to reach to the top of the sash. The inner or inside standard is of less height and carries the mechanism for reciprocating the cleaner. Y

The cleaning device proper comprises a sleeve port-ion slidablymounted on a standard, an arm extending therefrom, and a cleaner block detachably and pivotally connected to the end of thearm and equipped with meansfor attaching a cloth or other cleaning device thereto.

6 indicates the sleeve, and 7 the arm extending horizontally therefrom. Theend of the arm 7 is provided with a horizontally disposed cylindrical member 8 formed integrally therewith, and constituting means for attaching the cleaner'blo'ck.

.9 indicates the cleaner block, which is pref- I erably' rectangular, and provided upon its rear face with asplit sleeve 10, which slips longitudinally u on the member 8. If pre lay of the block may be permitted, the joint 8'10 acting as a pivot joint, or the oint may be rigid if preferred.

.11 indicates a pin extending through the sleeve 10 and an aperture 12 in the member 8 to prevent: accidental separation of the parts while in use,.and the sleeve is slotted to I receive the. in and permit play of the'block. In using 1; e device, the front face 13 of the block 9 is covered with'a'cloth, and to this end, the'block is equipped with means for securing the cloth thereto. This comprises a pair of metal strips 14 and 15 having upturned flanges 16 and 17 respectively, to which are secured a plurality of pins 18,

extending slightly? beyond the lower edge of the block. The clothis firstsecured to the pinson the flange 16 turned about the front face of the block and .then secured to the pins 18. It is obvious that the cloth is easil removed for andreplaced.

' those on the flanges 17 being adjacent to or- 19 indicates a roller arranged in the sleeve 6 at the base of the arm 7 to prevent friction between the sleeve and the standard when the device is pressed a ainst the window ane. Arranged upon the standard is a and wheel 20 having a handle 21 by means of which it is rotated. The band wheel 20 is connected by a cable 22 to .the sleeve 6 in i such a manner that by rotating the wheel, in

one direction, the sleeve will be raised, and by turning it in the opposite direction, the

sleeve 'will be lowered. To this end, the

cable or cord 22 passes down, and aboutthe rollersor pulleys 23-24 arranged within the base uponeach side of the standard 5, thence about similar rollers 25.an'd 26- in the base 1 upon each'side of the standard 4. The cord then passes upwardly and about a roller 27 arranged in a recess 28 at the upper end of the standard l.- To permit the cord or cable topass freely between the sill and sash, the base]. is longitudinally grooved as at 29 to receive the horizontal-portions of. the cable --20 is mounted.

between the rollers23 and 24, and 25 and 26. The standards 4: and 5 are arranged substantially on the central axis of the base which brings the band wheel- 20 to one side of its respective standard, whereas the roller, 27 is substantially-centralof the standard 4:, hence the groove 29 is arranged at an angle as shown clearly inFig. 2.

Suitable means are provided for taking up the slackof thecable 22. This comprises a pair of arms-30 and31 pivotally mounted upon the stud shaft 32 upon which the wheel These are provided at their lower ends with rollers 33-33, which rest against the outer edges of the cable.

34-34 indicate springs which draw the. rollers 33 tight against the cable, taking up the slack. These may either be attached to the standard 5 or to each other. As shown Having described myinvention what I.

claim as new, and desire to secure by Letter Patent, is:

3 1. In a device of the class described, a base in combination with a standard extending upwardly from the end thereof, a sleeve slid- I A ably mounted onsaid standard, a horizontal arm extending from said sleeve and having a horizontally disposed cylindrical member formed upon the end thereof, and a cleaner block having a split sleeve to engage said cylindricalw member, substantially as described.

2-. In a device of the class described a base block, in combination with a standard ex}- '1' tending verticallyv upwards from each end thereof, a cleanerslidably mounted upon oneof said standards, a band wheel mounted upon the other standard, a cable connecting .said cleaner and said wheel, a pair of arms pivotally mounted adjacent to said wheel and means for causing said arms to exert yielding pressure upon said cable, substantially as described. In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses. Y
